RV22 Subscriber App

In testing the RV22, we enter a email address into the Managed Subscribers form, we then receive an email with an access code and links to Apple + Google to download the App. Today we tested this, and when using the provided Google Play store link, we were not forwarded to the Google Play app, instead a download was initiated within the browser. The downloaded file, cnMaestro_Subscriber.apk, attempts to install upon opening, but a warning message pops up because it is from outside the App Store. Can this link be fixed?
We also found a grammatical error in the App. Screenshots attached.
